AgWeatherNet Weekly Weather Outlook for December 10 to December 16, 2016

Unsettled and Milder This Weekend; Colder and Drier Again Next Week

Nic Loyd, Meteorologist, 509-786-9357

The calendar claims that we are in December, and the weather is finally starting to follow suit with variable and sometimes wintry conditions.

Periodic rain is likely in the west this weekend, along with a chance of rain or snow at times in the east, although south central Washington should be mostly dry and breezy. Milder westerly air flow will cause temporary warming through at least Sunday, although the moderation may be short lived. Generally drier but colder weather is expected for next week, as more Canadian air infiltrates the Northwest. During the Monday transition time, a bit of lowland snow is still possible for some locations.

It is important to note that at some point later in the period, and perhaps as early as Tuesday, Washington may see even colder air than was experienced this past week. Arctic air is anticipated to linger north of the border in the coming days, but how much we receive is the critical question going forward. For any snow covered cold spots (east of the Cascades) that experience a clear and calm morning later next week, the potential exists for low temperatures around zero or just below, while chilly western areas could be in the teens.
